1 Claim.

This invention relates to a lamp guard and handle and particularly to means for securing a lamp guard to a handle.

An important object of the present invention is the provision of new and improved mean for detaching and attaching readily and quickly the lamp guard from the handle by the mere manipulation of co-operating elements so as to effect quick and easy replacement of a lam bulb which is threadedly received in the screw socket in the handle and within the guard or case.

Numerous other objects and advantages will be apparent throughout the progress of the iollowing specification.

The accompanying drawing illustrates a selected embodiment of the invention and the views therein are as follows:

Fig. l is a detail elevational view of a lamp guard and handle arrangement and embodying the invention;

Fig. 2 is a detail elevational view of the invention with the lamp guard removed; and

Fig. 3 is a detail sectional view on the line 3-3 of Fig. 1.

The particular lamp guard and handle herein shown for the purpose of illustrating the invention, comprises a handle I having a longitudinal bore 2 which receives a cable 3 containing electrical conductors, the conductors being electrically connected to a lamp socket 4 carried at the upper enlarged end 5 of the handle. The socket 4 may be of the conventional screw thread formation to receive threadedly the threaded end 6 of an electric lamp 1. The lamp 1 is protected by a lamp guard 8 which is connected releasably to the enlarged part 5 of the handle I.

The lamp guard 8, as shown, is made of fiber strips 9 extending longitudinally of the device, and these strips are connected at their tops to disks I and at their bottoms to a lower collar I I. A central intermediate or transverse member I2, also made of fiber, is fastened to the strips 9 to strengthen the guard and add rigidity thereto. Fasteners, such as rivets l3, secure the strips 9 to the parts or members I0, II, and I2. The guard 8 may. of course, be made of metal, such as wire, instead of fiber as herein shown.

There have been many ways of securing lamp guards to handles, but all conventional methods require too much time and energy to remove the guard from the handle for the purpose of removing or placing a lamp. The average mechanic or other user of a lamp and guard handle is adverse to spending time and effort for the simple procedure of putting a new lamp in a socket, and

therefore, the more simple and efflcient the attachment is, the more suited it is for the purpose. The present invention provides an extremely simple and efilcient device which is capable of being readily operated or manipulated so that the guard may be detached quickly from the handle. The means employed in the present invention for releasably or detachably connecting the guard to the handle comprises two or more integral spring members or clips I4 which are secured to the enlarged part 5 of the handle I. One clip I4 may be used in conjunction with some other type of fastener if desired. 7

Each spring clip I4 has a straight body portion I5 conforming to the inclined surface I6 on the lower side of the body enlargement 5 to which it is attached by fasteners, such as screws I1. A part I8 of the clip is integral with the straight part I5 but slopes somewhat inwardly, not being quite as inclined as the part l5. An inturned part I9, being integral with the parts I5 and I8, provides a locking ledge or catch and forms a recess 20 for the collar II of the lamp guard 8. An outwardly extending or flaring part 2|, also integral with the other parts of the clip, provides a member which can be operated manually to release the spring clip or catch from the collar II. The shape of the part 2| also allows for application of the guard to the handle by merely pushing the guard downwardly, whereby the collar will press the clips outwardly until in final position, whereupon the ,collar will be home in the recess 20, and the latch part I9 of the clip will be locked over the upper edge of the collar. The guard is released, therefore, merely by pressing the part 2| to disengage the locking or latching part I9 from the upper edge of the collar, thereby permitting easy and quick detachment of the guard to permit lamp replacement. The guard is re-applied in place merely by pushing the guard downwardly, whereupon the clips will give because of their resiliency and then snap back in home position. The upper end of the handle is provided with an annular recessed part to facilitate easy application of the guard to provide an annube operated with the utmost ease and in a very short time.

spaced guard members secured on said collar,

said enlargement forming a seat for receiving the collar, and a one-piece yieldable spring clip fas-- being provided with an ofiset portion forming a recess for the collar and a latching portion adapted to enter the space between a pair of said guard members in position to engage the upper end of the collar and latch the collar detachably in the seat, said spring clip being attached to the handle only at its end remote from said latching portion to permit the clip to be flexed whereby said latching portion will be free to snap over the upper edge'oif the collar and flatfli the :guard detachably to the handle when the "guard is applied to,

the handle, the clip flexing to accomplish the latching action.
